The Enterprise Edition is a robust solution that can either be hosted by a school or can be accessed online by students (through a version that will be hosted by McGraw-Hill). The Enterprise Edition includes all of the functionality in the Instructor Program (for SimNet XPert Standard Edition), and all of the functionality in PageOut (for SimNet XPert PageOut Edition) in an easier to use program. And the Enterprise Edition adds new functionality, like a complete new administrator level!
